ABSTRACT

A tonneau system that includes one or more tonneau sections and a retraction system. The retraction system has an adjuster shaft; a bias member; a drive roller in communication with the adjuster shaft; one or more lines connected to the one or more tonneau sections and/or to the drive roller; and an adjuster to adjust torque provided by the bias member. The bias member is connected to the adjuster shaft, the drive roller, or both.

FIELD

The present teachings relate to a truck bed cover that is a hingedtonneau system with a plurality of tonneau sections that are foldablerelative to each other and specifically a truck bed cover that isconnected to a cable, which regulates movement of the truck bed coverbetween an open position and a closed position.

BACKGROUND

Tonneau systems cover an open area of a vehicle and generally cover anopen area of a pick-up truck (i.e., a bed). Multiple different types oftonneau systems are available, with some of the tonneau covers beingsolid and opening about a pivot, some folding upon themselves, andothers rolling up. With the roll up type covers, as the cover begins toroll up an amount of force required to store the cover graduallydecreases. In some instances, the cover may begin to extend to a storageposition and the user may have to resist movement of the tonneau covertowards the storage position. Conversely, upon removal of the cover fromthe storage position, the user may have to exert a large amount of forceand as the tonneau cover deploys an amount of force may graduallydecrease. Further, in moving between a stored position and a deployedposition the tonneau cover may not be fully supported by a portion thatcovers a tail gate and thus the tonneau cover may sag. A sag in thecover may require user assistance to guide the tonneau into a closedposition. Finally, the tonneau covers, in a closed position, may preventwater from entering the bed of a vehicle. When water and debris landupon the tonneau cover, the water may pool upon the cover so that uponopening the cover some of the water may enter the bed of the vehicle.

Examples of tonneau systems are found in U.S. Pat. Nos. 4,889,381;4,563,034; 4,786,099; 4,792,178; 5,251,950; all of which are expresslyincorporated herein by reference for all purposes. It would be desirableto have a retraction system that both assists in storing a tonneau coverand deploying a tonneau cover. What is needed is a retraction systemthat maintains a substantially constant amount of force upon an entireclosing movement, an entire opening movement, or both. It would bedesirable to have one or more pulleys that adjust upon travel of thetonneau cover within a canister that stores the tonneau cover. What isneeded is a connection system with one or more connectors that connect atonneau cap to one or more tonneau sections. It would be desirable tohave one or more tail supports that assist the tonneau cap with forminga connection with an end of a bed or a tailgate of a bed without needinguser assistance to extend the tonneau cap over the end or tailgate. Whatis needed is a tonneau system with a plurality of drain features thatassist in removing water from the tonneau system so that the bed remainsdry.
